Simulative debugging platform special for frequency converter of building hoist

The invention discloses a simulative debugging platform special for a frequency converter of a building hoist. The simulative debugging platform is connected at two ends of a power supply and comprises a simulative door limit circuit, a simulative rising circuit, a simulative declining circuit, a free parking indication circuit, a low-speed indication circuit, a limit indication circuit and a brake opening circuit which are connected at two ends of the power supply and connected with each other. The simulative door limit circuit comprises a simulative door limit switch and a door limit indication light which are in serial connection. The simulative rising circuit comprises a first intermediate relay and a rising indication light. The first intermediate relay is serially connected with a first normally-closed switch, a first simulative upper limit switch and a simulative rising switch and then is connected onto the power supply end. The rising indication light is connected with the power supply end through a first relay control switch. The first intermediate relay controls turning on and off of the first relay control switch when being powered on. The simulative debugging platform can simulate all work conditions of the frequency converter of the building hoist, and avoids mistaken circuit connection of a frequency conversion system of the building hoist during ex-factory debugging.
